LIGI-IT-CONITECTICN TERMINAL.

Application filed October 14;, 1921.

T 0 all whom it may concern Be it known that I, LA VERNE I-I. BEAM, a. citizen of the United States, residing at the city and county of Kalamazoo, State of liIichigan, have invented certain new and useful Improvements in Light-Connection Terminals, of which the following is a specification.

This invention relates to improvements in elect 'ic connections for automobile lights and the like.

The object of the invention is to provide a structure which can be very readily connected and which is very secure and protected when in place, not depending upon screws to retain it in position.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a. preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this application, in which:

Fig. I is a detail elevation view substantially full size of my improved coupling in connection with a regulation lightsocket.

Fig. II is an enlarged detail sectional elevation view taken on irregular line 2-2 of Figs. I, III and V.

Fig. III is an enlarged detail cross sectional View taken on irregular line 33 of Figs. I and II.

Fig. IV is a detail elevation view of the protector cap removed.

Fig. V is an enlarged detail view, partially in section, taken on line 55 of Figs. I and II.

Fig. VI is a detail sectional view taken on line 6-6 of Figs. II and V showing the contact of my improved connection with the socket plug of a lamp.

Fig. VII is a detail sectional view similar to that ap aearing in Fig. III where a grounded circuit is used.

Fig. VIII is an end view of the core as sectioned in Fig. VI.

In the drawings similar reference characters refer to similar parts throughout the several views and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Serial No. 507,717.

Considering the numberedparts of the drawing by number, 1 is a tubular lamp socket; 2 is the lamp; 3 is the bayonet joint slot to receive the pin l constituting the bayonet joint connection therefor; 5 is the electric conductor and contact; and 6 the central carrying insulating plug. Those parts thus far enumerated are of the usual construction and need not be described in detail.

My improved connection consists of a central insulating core 7 provided with lateral pins 8 which engage slot 9 in the back end of the tubular socket 1. The electric lamp contact pins are extended to the rear at 10 and are provided with a pair of electric conductors and contacts 11 disposed in suitable longitudinal bores 12 in the said core. These contacts are each made up of a. strip of copper or brass folded upon itself, having a downturned contact end 11. The rear or other end 11 projects beyond the folded end 13 in close relation thereto to receive and closely embrace the end 14 of the electric conductor wire to be connected.

The core has a central extension 7 to afford substantial support for these projecting ends and insure their securely grasping the electric conductor wire ends 14:. A slip cap 15 with 21 notched opening 16 on its under side for the wire or wires embraces and protects these terminals from injury and moisture.

Lateral pins 17 are provided on the sides of the cylindrical core 7 and engage in suit able bayonet slots 18 in said cup to effectively retain the same in place, thus avoiding the necessity of a screw fit and insuring a. complete cap over the ends of the exposed or uncovered wires.

With the usual construction a. pair of contacts is provided but where the circuit is grounded only a single connection 11 need be provided, as indicated in Figs. VII and VIII.

I have shown my invention in preferred form and desire to claim the same specifically and also broadly as pointed out in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. The combination with an electric light socket of a rearward extension, an insulating core block with bayonet joint for con bayonet joint" nection thereto containing longitudinal openings, electric conductors disposed in the said openings each composed of a flat strip of metal with a down-turned end forcontact with a lamp connection and folded upon itself at the other end to form an embracing portion for a Wire end, constituting a connection therefor, the core being extended at its center to form a support for the folded end, and -a horizontally disposed cap open on the under side for the passage of said wire and embracing the said con nection, provided with 'a bayonet joint to retain the same upon and embracing the said connections and core.

2. An electric light plug comprising an insulating core, a strip of metal disposed therethrough with down-turned contact end, the opposite end folded upon itself at the other end to embrace the circuit wire end to constitute a connection therefor, a horizontally disposed cap open on the under side with notch aperture for the passage of said wire, and a suitable bayonet joint for retaining the said cap on the said core.

3. An electric light plug comprising an insulating core, a strip of metal disposed therethrough with down-turned contact end, the opposite end folded upon itself to embrace the wire end of the circuit, a horizontally disposed removable cap open on the under side with notch aperture for the passage of said wire.

4;. An electric light plug comprising an insulating core, a strip of metal disposed therethrough with down-turned contact end, the opposite end folded upon itself to embrace the Wire end of the circuit, protecting means therefor comprising a horizontally disposed removable cap with notch aperture on its under side.

In witness whereof, I have hereunto set my hand and seal.
